Letter to the Editor: How did Patriot Act evolve from ;specific warrant' to 'general'?

How did the Patriot Act evolve from "Specific Warrant" (Bush) to "General Warrant" (Obama)?

It is one thing to wiretap, etc., using "specific investigative warrants" as in the Bush era, but what we have now are "general warrants," which literally can involve all U.S. residents! For example, every email, text, blog and phone call can be accessed by the government via this "General Warrant!" That is exactly what the new 1 million-square-foot NSA complex 25 miles from Salt Lake City is being built for!
